總部位于澳大利亞的解剖學是早期在手術中使用3D打印的先驅。在神經外科醫生保羅德烏索（Paul D’Urso）的領導下，該公司在個性化植入、手術計劃和3D打印醫療設備方面做了大量工作。在胸外科、CMF植入物和整形外科，該公司推出了軟件解決方案以及供外科醫生使用的植入物和材料。患者專用手術工具、患者專用脊柱籠、胸骨或設計手術植入物的軟件。
現在，解剖學家與新加坡的Tan Tok Seng醫院合作，進行了世界首創的聚合物胸腔鏡重建術。使用解剖的StarPore聚合物組織支架，一名需要新胸腔的26歲癌症患者得到了幫助。手術很成功，病人兩天後就回家了。除了3D打印的胸腔重建術本身之外，還創建了針對患者的手術指南，醫學模型以及切割指南和模板，以輔助手術。
StarPore具有“強度、靈活性及其允許細胞和組織向內生長的能力”。StarPore腳手架將維持患者的壽命，同時保持其形狀不變，並用天然組織將其固定在適當的位置。由于生物小梁的孔隙率與人體相似，該材料爲人體組織提供了一個可以抓緊並生長的支架。”
這項手術由譚托克森醫院胸外科主任阿內茲·艾哈邁德博士和他的團隊進行。艾哈邁德博士表示，
“在這種情況下，沒有與StarPore解決方案相提並論的東西。由于沒有其他選擇，因此StarPore解決方案絕對可以改善患者的健康狀況……Anatomics解決方案的一個重要優點是易于使用。我們不再像傳統方法那樣一次做一根肋骨，而是切開並分離了患處的胸壁，輕松地插入了植入物，從而使重建變得非常容易。“解剖學個性化解決方案的幫助取得了成功。通常的胸壁重建平均需要大約4-6個小時。我們能夠在大約兩個半小時內完成此案例”
長期以來，針對患者的植入物一直被吹捧爲植入物和骨科的未來。從理論上講，它們應該導致更快的手續，更少的失血和更快的恢複時間。在某些情況下，這可能是正確的，而在其他情況下，標准植入物就足夠了。然而，對于新穎的手術程序，將3D打印與數字化手術計劃相結合已成爲一條通往未知和重大新成果的久經考驗的道路。此處看到的集成方法將使該過程有些不適，並使執行計劃更加清晰。我認爲，第一次合適的東西是有價值的，但絕對知道個性化的切割指南和特定的標簽是有價值的，以確保減少錯誤；特別是長時間的、新的或複雜的程序。

Singapore: World’s First 3D Printed PolymerRibcage Reconstruction
Australia based Anatomics was an early pioneer in using 3D printing forsurgeries. Under Neurosurgeon Paul D’Urso the firm has done a lot of work in personalized implants,surgical planning and 3D printed medical devices. In thoracic surgery, CMFimplants and orthopedics the firm has rolled out software solutions as well asimplants and materials for surgeons to use. Patient-specific surgical tools,patient-specific spinal cages, sternums orsoftware to design surgical implants.
Now Anatomics worked with Singapore’s TanTok Seng Hospital to do a world-first, a Polymer ribcage reconstruction. UsingAnatomics’ StarPore polymer tissue scaffold a 26 year old cancer patient whoneeded a new ribcage was helped. The surgery was a success and the patient wenthome after two days. In addition to the 3D printed ribcage reconstruction itself,patient-specific surgical guides, medical models and cutting guides andtemplates were also created to aid the surgery.
The StarPore has, “strength, flexibility and its capacity to allow cell andtissue ingrowth. StarPore scaffolding will last for a patient’s life spanwhilst keeping the same shape, with natural tissue holding it in place. Thematerial provides a scaffold for human tissue to grab onto and grow into, dueto biological trabecular porosity similar to that found in the body.”
The surgery was conducted by Dr Aneez Ahmed,Head of Service of Thoracic Surgery at Tan Tock Seng Hospital, and his team. DrAhmed says that,
“There’s nothing like a like for like comparison with theStarPore solution for this case. Thus the StarPore solution definitely improvesthe patient’s health outcome as there is no alternative possible…An importantadvantage of the Anatomics solution was the ease of use. Instead of doing onerib at a time, multiple times, in the conventional way, we cut out and detachedthe affected chest wall and inserted the implant easily, making thereconstruction very easy. “The Anatomics personalized solution (StarPoreimplant, BioModel, 3DP cutting guide and 3DP implant positioning template)helped achieve the success. The usual chest wall reconstruction takes anaverage of about 4-6 hours. We were able to do this case in about two and ahalf hours”
Patient-specific implants have long been touted as the futureof implantology and orthopedics. Theoretically, they should result in quickerprocedures, less blood loss and faster recovery times. In some cases, this maybe true while in others a standard implant could suffice. In the case of novelprocedures however 3D printing coupled with digital surgical planning isbecoming a tried and tested route to the unknown and big new results. The integratedapproach seen here would derisk the procedure somewhat and make planning anexecution much clearer. I would assume that there would be value in somethingfitting right the first time but absolutely know that there is value inpersonalized cutting guides and specific labeling to make sure that errors arereduced; especially with lengthy, new or complex procedures.
